Device including a lens array

Abstract

An evaluation device includes more than three images showing at least two different appearances of keratinous materials, each of the images including an identifier; and an optical system that is configured to make the different images appear in succession as a result of a change in the angle of observation of the device.

1 . A device comprising:
 more than three images showing at least two different appearances of keratinous materials, each of the images including an identifier; and   an optical system that is configured to make the different images appear in succession as a result of a change in the angle of observation of the device.   
   
   
       2 . A device comprising:
 at least two images showing at least two different appearances of keratinous materials, each of the images including an identifier; and   an optical system that is configured to make the different images appear in succession as a result of a change in the angle of observation of the device, the identifier comprising a marker that is associated with a scale that is situated outside the optical system.   
   
   
       3 . A device comprising:
 at least two images showing at least two different appearances of keratinous materials, each of the images including an identifier;   an optical system that is configured to make the different images appear in succession as a result of a change in the angle of observation of the device; and   an opening making it possible to juxtapose keratinous materials and at least one image that is observed on the device.   
   
   
       4 . A device comprising:
 at least two images showing at least two different appearances of keratinous materials, each of the images including an identifier; and   an optical system that is configured to make the different images appear in succession as a result of a change in the angle of observation of the device;   the device being associated with at least one composition, and the identifier providing information about the use of the composition.   
   
   
       5 . A device according to  claim 1 , the optical system including a lens array. 
   
   
       6 . A device according to  claim 1 , the images showing at least two different degrees of a characteristic of the keratinous materials. 
   
   
       7 . A device according to  claim 6 , the characteristic being at least one member selected from the group consisting of:
 a characteristic relating to aging; a physical or morphological characteristic; color of the skin or of the hair; typology of the eyelashes or of another region of the face or of the body; color of the teeth; and color of eye lenses.   
   
   
       8 . A device according to  claim 7 , wherein the characteristic relating to aging is at least one member selected from the group consisting of a number and depth of wrinkles; sagging of the skin; number and depth of folds; creasing of the skin; depth of dark rings; level of cellulite; ptosis; and blemishes on the skin. 
   
   
       9 . A device according to  claim 8 , wherein the characteristic relating to aging is at least one member selected from the group consisting of sagging of the skin in the neck and a number and depth of folds in the neck. 
   
   
       10 . A device according to  claim 7 , wherein the physical or morphological characteristic is at least one member selected from the group consisting of a number and size of corneoparticles of the skin; sebum secretion level; sweat secretion level; dryness of the skin or the lips; length, curvature, or density of the eyelashes or the hair; blood supply of the skin; pigmentation defect; density of blackheads; acne; blotches; moles; and outline of the lips. 
   
   
       11 . A device according to  claim 1 , the different images showing different makeup effects for the body or for the face. 
   
   
       12 . A device according to  claim 2 , including more than three images. 
   
   
       13 . A device according to  claim 1 , including more than ten images. 
   
   
       14 . A device according to  claim 1 , the identifier including at least one alphanumeric character. 
   
   
       15 . A device according to  claim 1 , the identifier comprising a marker that is associated with a scale that is situated outside the optical system. 
   
   
       16 . A device according to  claim 1 , including an opening making it possible to juxtapose keratinous materials and at least one image that is observed on the device. 
   
   
       17 . A device according to  claim 1 , being associated with at least one composition, and the identifier giving information about the use of the composition. 
   
   
       18 . A package for packaging a cosmetic composition or a food supplement, the package including a device comprising:
 at least two images showing at least two different appearances of keratinous materials, each of the images including an identifier; and   an optical system that is configured to make the different images appear in succession as a result of a change in the angle of observation of the device.   
   
   
       19 . A method of manufacturing a device including at least two images showing at least two different appearances of keratinous materials, each of the images including an identifier; and an optical system that is configured to make the different images appear in succession as a result of a change in the angle of observation of the device, the method comprising:
 receiving at least a first image of keratinous materials of a subject from said subject, or acquiring the first image of keratinous materials of said subject;   generating at least a second image at least on the basis of the received or acquired first image; and   producing the device including at least the generated second image.   
   
   
       20 . A method according to  claim 19 , the second image being generated by image synthesis. 
   
   
       21 . A method according to  claim 19 , in which a plurality of images are generated that correspond to different makeup effects or to different treatments or stages of a treatment.
